Sysupdate Required Error

Prior to v3.0, with the atumn and sun domains blocked, the system could be used with online services on non-latest system-versions fine. As of roughly the day following the release of v3.0 however, the system being on >=v3.0 is now enforced via an account-related domain. This affects everything using Nintendo-accounts, regardless of whether the current user has one linked or not.

This also affects launching the WifiWebAuthApplet on pre-v3.0. Error 2110-3400 is thrown while eShop is loading, with the conntest domain setup to trigger the web-applet(originally launching eShop could be used for triggering the WifiWebAuthApplet). When attempting to connect to wifi from System Settings on versions >=v2.1(?), it will display the "Registration required ..." message then display a separate sysupdate-required message(different from the error message) before the web portal. With the dauth domain blocked, eShop has the same failure, however System Settings will launch the web-applet after it displays the "Registration required ..." message when connecting to wifi.

Hence, all web-applets for anything Nintendo-account related is rendered unusable on <v3.0. Web-applets not using Nintendo-accounts still work fine.
